Brotli is a generic-purpose lossless compression algorithm that compresses 
data using a combination of a modern variant of the LZ77 algorithm, Huffman 
coding and 2nd order context modeling, with a compression ratio comparable 
to the best currently available general-purpose compression methods. It is 
similar in speed with deflate but offers more dense compression.

This update contains a secuity update, which fixes an "integer overflow" problem [1].
And, a new package python38-brotli-1.0.9-1 for python38 bindings.
